WATER-RESERVOIR FOR STOVES.

SPECIFICATION forming part of Letters Patent N o. 643,136, dated February 13, l1900.` Application iled April 17, 1899. Serial No. 713,425. (No model.)

To a/ZZ whom it may concern:

Be it known that we, ROBERT 4Lun Hons- LEY and JAMES I-I. ROUNTREE, citizens of the United States, residing at Whitney, county of Hill, and State of Texas, have invented a new and useful Improvement in Water-Reservoirs for Stoves, to be known as the Top Reservoir, which is fullyset forth in the following specitication, reference being had to the annexed drawings.

This invention relates to waterreservoirs, and more particularly to that class adapted for heating water in connection with a common form of stove in which the smoke-pipe is exposed.

One object of the invention is to provide a reservoir which will have such shape as to occupy a minimum of space upon the top of the stove about'the smoke-pipe and which will at the same time hold a maXimumofwater without interfering with the placing of tall vessels upon the stove.

A further object of the invention is to so form the reservoir as to insure an efficient circulation of water during the heating operation and in which the bubbling at the surface of the water will not have a splashing eifect, the upper end of the reservoir being extended laterally to form a shelf.

In the drawings forming a portion of this specification, aud in which similar numerals of reference designate corresponding parts, Figure 1 is a perspective view of the reservoir applied to a stove. Fig. 2 is atransverse section of the reservoir and connected portions of the stove and stovepipe.

Referring now to the drawings, the reservoir consists of a base 5, which may have any desired outline, although in this instance it is shown as rectangular and oblong. From the sides of the base 5 there are extended upwardly the side pieces 6, which are similar in form and the side edges of which lie parallel for a distance of substantially twothirds of its height, after which the side edges are diverged, as shown. From the ends of the base 5 are extended upwardly additional side pieces 7, having parallel side edges and which are soldered or otherwise secured to the edges of the side pieces 6, the result being a receptacle having a constant rectangular cross-section throughout the lower twothirds of its height and above which it is gradually expanded throughout the remainder of its height.

Fixed to the upper edges of the side pieces 6 is a single top section secured at its ends to said side pieces, said top section having lids 9 hinged to its side edges and adapted, in connection with the said top section, to form a complete cover or lid for the receptacle.

Centrally of the bottom 5 is formed an elliptical opening, the major diameter of which lies in the direction of iiare of the receptacle, and registering with this opening is a circular opening 10 in the top section 8. Connecting the openings 10 and 11 is a tube 12, the lower end of which is elliptical and the upper end of which is circular, and which" tube forms a vertical passage through the receptacle.

In one side 6 of the receptacle is entereda faucet 14, near the lower edge thereof, and through the medium of which water which has `been contributed to the vessel through thetop may be withdrawn.

In practice the receptacle is disposed with the tube 12 to receive the projecting elliptical tube upon a stove and to which the stovepipe is ordinarily connected, and into the upper end of the tube is passed the end of a stovepipe 15, or, if desired, the receptacle may be disposed with the tube 12 upon the stovepipe. A quantity of Water is then placed within the receptacle and preferably to reach adjacent the upper end thereof, which water will receive heat through the tube 12, as will be readily understood.

With the interior shape of this device there will be an ecient circulation of water, the water directly adjacent the tube or pipe 12 rising along the surface of said tube or pipe, from which it will pass outwardly, due to the bubbling of the water and to the well-known laws of circulation of water when heated, and ,will then pass downwardly of the surface of the receptacle and to the bottom thereof, when it will again rise along the surface of the tube.

It will be noted that the bottom of the tube 12 is separated' from the walls of the receptacle by an interspace and that the tapering of the tube results in a gradually upwardly expanding effective cross-section 'of the re-x IOO ceptacle. Owing to this construction there is a minimum retarding of the upward flow of water by the cooler water falling at the wall of the receptacle and a resultant more efficient circulation. Moreover, as each particle of water rises it is added to the quantities rising thereabove, so that the cross-section of the rising column increases upwardly. This is compensated for by the gradual expansion of the effective cross-section. Furthermore, the flared upper end ot' the vessel prevents any objectionable eiects of bubbling, as will be readily understood, and at the same time the specific shape of the vessel enables it to hold a maximum quantity of water While occupying a minimum of space upon the top of the stove and without interfering with the placing of tall vessels.

It will thus be seen that the structure presented accomplishes the results for which it is designed and that' the efficient circulation ROBERT LEE HORSLEY. JAMES H. ROUNTREE.
